[Industrial applications]

 The present invention relates to a vehicle wind molding mounted in a gap between a vehicle body panel and a peripheral edge portion of a window glass fixed to a window opening of a vehicle body panel of the vehicle, and a method for manufacturing the same.

[0002]

[Prior art]

 Generally, a wind molding is attached to a peripheral portion of a window glass attached to a window opening of a vehicle body panel. Specifically, a continuous elongated gap is formed between the peripheral edge of the windshield and the opening edge of the window opening of the vehicle body panel. Wind molding is fitted and the seal is done. The wind molding is usually molded from an elastomer such as rubber or resin, and is inserted into the above-mentioned gap and fitted to a predetermined portion, and the above-mentioned gap is provided at the vehicle outer end of the leg. And a decorative portion that covers the vehicle from outside the vehicle. For such a wind molding, it is preferable to use a material having higher rigidity from the viewpoint of workability in attaching to the vehicle body panel side, posture retention, and the like.

On the other hand, it has been conventionally proposed to provide a groove for blocking and draining rainwater on the windshield on the side portion of the wind molding. For example, Japanese Utility Model Publication No. 57-54416, Japanese Unexamined Patent Publication No. 63-291721 (US Pat. No. 4,757,660), Japanese Unexamined Patent Publication No. 1-195032 (US Pat. No. 4,865,796), Japanese Patent Publication No. 1-223018 and Japanese Utility Model Publication No. Nos. 1-144109 (US Pat. No. 4,984,839) and JP-A-3-128721. In an automobile wind molding equipped with such a rainwater receiving groove, since the part that can be raised apart from the surface of the wind glass is constructed, it is necessary to particularly improve the rigidity of the material.

[0004]

[Problems to be solved by the device]

 However, if the entire wind molding is formed of a high-rigidity material in order to improve the rigidity of the wind molding, there is a problem in that the bending workability of the corner portion is deteriorated at the time of mounting. Various proposals have been made in Japanese Utility Model Laid-Open No. 58-73014, Japanese Patent Laid-Open No. 59-8523, Japanese Patent Laid-Open No. 60-248426, and the like for properly bending the corner portion. Since the number of steps for molding and mounting is increasing, there is a problem in terms of productivity, and there is also a problem in that it has to be stored in a bent state during transportation, which requires a large storage space. Further, JP-A-1-145223 (U.S. Pat. No. 4,964,543) discloses an insert of an iron core to impart rigidity, but it requires a large mold and also has the above-mentioned problem of transportability. is there.

Therefore, the present invention can obtain good decorativeness, wearability, and transportability while increasing the rigidity of the molded portion of the rainwater receiving groove, that is, the portion separated from the windshield surface, and can be easily and continuously connected. It is an object of the present invention to provide an automobile wind molding that can be molded.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, an automobile window molding according to the present invention comprises an inner peripheral edge of a window frame opening provided on a vehicle body panel and a corner from a window glass upper portion fixedly attached to the window frame opening of the vehicle body panel. A main body molding to be mounted in a gap between the peripheral portion passing through the section and extending to both side portions, and the main body molding described above includes a leg portion fitted into the gap and the leg portion. A decorative portion which is provided at the vehicle outer side end and covers the gap from the vehicle outer side, and at least the decorative portion at the side portion is separated from the surface of the windshield toward the vehicle outer side and In an automobile wind molding having a rainwater receiving groove defined therein, the leg portion and the decorative portion of the main body molding are formed of a series of extruded members over the entire length, and the decorative portion At least the outer surface of the vehicle is made of the same material over the entire length, and at least the portion corresponding to the corner of the leg is made of a material having flexibility as compared with the portion where the rainwater receiving groove is provided. have.

[0007]

[Action]

 According to the means having such a structure, the rigidity of the rainwater receiving groove forming portion is enhanced by the hard material, and at the same time, the bendability at the corner portion is secured by the soft material. At that time, since at least the exterior surface portion of the decorative portion is formed of the same material over the entire length, the appearance design of the molding is maintained in a seamless series of design states.

【Example】

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. First, as shown in FIG. 1, a main body molding 2 which is a window molding made of a long extruded seal member is attached to a peripheral portion of a windshield 1 on the front side of an automobile. The main body molding 2 is provided in the gap between the upper edge of the windshield 1 and the roof panel 3 and the gap between the side edges of the windshield 1 and the pillar panel 4. It has a mounted side molding 2C and a corner molding 2B that connects the upper molding 2A and the side molding 2C in a curved shape, and these moldings 2A, 2C, 2B are integrally and continuously extruded. It is molded.

The main body molding 2 is formed by integrally extruding an elastic material such as rubber or synthetic resin into a long strip shape by a predetermined molding device. As shown in FIGS. 2 to 6, It has a leg portion 22 inserted in a gap between the peripheral edge portion of the window glass 1 and the roof panel 3 and the pillar panel 4, and the end of the leg portion 22 on the vehicle outer side (upper side in FIGS. 2, 3 and 4). In addition, the decorative portion 21 is provided to cover the surface of the windshield 1 and the surfaces of the roof panel 3 and the pillar panel 4 from the outside of the vehicle. The decorative portion 21 and the leg portions 22 form a substantially T-shaped cross section orthogonal to the longitudinal direction.

In the leg portion 22, a metal thin foil core metal 23 as a core material is embedded in the vicinity of a connecting portion with the decorative portion 21. Further, a first support piece 24 and a first elastic lip piece 25 are provided on the inner edge and the outer edge of the side portion of the leg portion 22 on the vehicle inner side edge (lower edge in FIG. 4), respectively. In addition, a second support piece 26 and a second elastic lip piece 27 are provided on the inner peripheral side and the outer peripheral side of the leg 22 in the middle of the inside and outside of the vehicle. The first support piece 24 and the first elastic lip piece 25 are arranged only in the side portion, not in the upper portion and the corner portion. That is, the first support piece 24 and the elastic lip piece 25 are once extruded over the entire length of the molding as shown in FIG. 5, and thereafter, as shown in FIG. A part of the portion 22 is removed by a predetermined cutting process.

On the other hand, the second support piece 26 is arranged in the side portion and the upper portion, and is not provided in the corner portion. Similar to the first support piece 24 and the elastic lip piece 25, the second support piece 26 is once extruded over the entire length of the molding (FIG. 5), and then is cut into a corner portion by a predetermined cutting process. The part has been removed (Fig. 6). On the other hand, the second elastic lip piece 27 is not cut off at all, and the second elastic lip piece 27 is arranged over the entire length of the side portion, the corner portion, and the upper portion.

The leg 22, the first support piece 24 and the first elastic lip piece 25, and the second support piece 26 and the second elastic lip piece 27 cross each other at right angles to the longitudinal direction. The surface is integrally formed of the same resin material, but the material is changed along the longitudinal direction. That is, the side molding 2C is made of a resin material P1 having a relatively high hardness, and the corner molding 2B and the upper molding 2A are more flexible than the resin material P1 of the side molding 2C. Is formed of a resin material P2. As the resin material P1 having hardness, for example, a material in which glass fibers are folded is used.

On the other hand, the decorative portion 21 has a glass-side decorative portion 21a and a panel-side decorative portion 21b which extend from the vehicle outer side end of the leg portion 22 to the window glass 1 side and the vehicle body panels 3 and 4 side, respectively. ing. The glass-side decorative portion 21a is formed of a lip-shaped member that covers the vehicle exterior surface of the windshield 1, and the panel-side decorative portion 21b is formed of a lip-shaped member that abuts on the vehicle exterior surface of the vehicle body panel 3. ing. The vehicle exterior surface layer portion of such a decorative portion 21 is formed of the same material over the entire length, and a resin material P3 different from the above-mentioned leg portion 22 and the like is adopted. The glass-side decorative portion 21a and the panel-side decorative portion 21b are set to have a uniform thickness and shape over the entire length of the molding.

The vehicle body side mounting structure of the window glass 1 using the main body molding 2 will be described below. The inner peripheral edge portions of the glass mounting openings provided in the roof panel 3 and the pillar panel 4 are bent in a stepwise manner toward the indoor side so as to receive the windshield 1, and the folding walls 3a and 4a are formed. Flange portions 3b and 4b are provided through the. The rising height of the bent wall 3a of the upper part is made uniform, but the rising height of the bent wall 4a of the side part is gradually increased from the middle of the corner part.

Then, first, the auxiliary mole 3 is attached from the corner portion to the side portion of the main body molding 2 described above. The sub molding 3 is attached to the inner corner of the joint between the glass side decorative portion 21a of the molding main body 2 and the leg portion 22, and is engaged with and held by the second support piece 26 of the molding main body 2. The portion corresponding to the side portion of the auxiliary molding 3 is formed into a certain cross-sectional shape that fits into the support piece 26, and the cross-sectional shape of the portion corresponding to the corner portion is similar to that of the main molding 2 and the window. It is continuously changed to fill the gap with the glass 1. The portion corresponding to the corner portion is molded by injection molding or the like, and is made of a relatively flexible material P2, like the leg portion 22 and the like described above. Further, the portion corresponding to the side portion is made of the material P1 having a relatively high hardness.

Next, the strip-shaped dam rubber 14 is fixed to the flange portions 3b and 4b on the windshield 1 side or the vehicle body panels 3 and 4 side, and the adhesive 15 is extruded on the outer peripheral side of the dam rubber 14 by extrusion. Is filled. Then, the inner surface of the window glass 1 is brought into contact with and pressed against the dam rubber 14. As a result, the window glass 1 is fixed on the flanges 3b, 4b on the vehicle body panels 3, 4 side at a substantially uniform height all around, and the outer surface of the windshield 1 and the vehicle body panels 3, 4 are secured. A step corresponding to the rising height of the bent walls 3a, 4a is formed between the surface and the surface.

In this state, the wind molding is fitted in the gap formed between the peripheral portion of the windshield glass 1 and the vehicle body panels 3, 4. At this time, in the upper part of FIG. 2, the part between the support piece 26 of the upper molding 2A and the glass side decorative part 21a is fitted to the upper edge part of the window glass 1 and at the side part of FIG. The portion between the support piece 24 of the side molding 2C and the glass side decoration portion 21a is fitted to the side edge portion of the windshield glass 1 via the sub molding 3. Further, in the corner portion of FIG. 3, a part of the auxiliary molding 3 is inserted between the glass side decorative portion 21a of the corner molding 2B and the window glass 1. On the other hand, the elastic lip pieces 25 and 27 are elastically contacted with the bent walls 3a and 4a by a bent body. The glass-side fitting force of the support pieces 24 and 26 and the elastic repulsive force due to the bending of the elastic lip pieces 25 and 27 act as a temporary fixing force and a posture holding force until the adhesive 15 is solidified.

By mounting the wind molding, the corner molding 2B is curved to have a predetermined curvature. However, since the corner molding 2B is made of the flexible material P2 as described above, it can be bent and mounted. The work is performed extremely well, and there are no problems such as wrinkles due to the difference in bending circumference.

In such a mounted state of the molding, first, in the upper portion (see FIG. 2), there is almost no step difference between the windshield 1 and the vehicle body panel 3 over the entire length, and therefore, the glass side decorative portion 21a is the windshield 1. Is adhered to the surface of. In the corner portion (see FIG. 3), the glass-side decorative portion 21a has begun to be separated from the surface of the window glass 1 by inserting the sub-molding 3 in correspondence with the gradually increasing step. . The step is gradually enlarged from the middle part of the corner portion toward the side portion, and the insertion height of the sub molding 3 is gradually enlarged toward the side corresponding to the variation of the step. The amount of separation of the glass-side decorative portion 21a also gradually increases toward the side. Further, in the region near the center of the side portion in the longitudinal direction (see FIG. 4), the insertion height of the auxiliary molding 3 and the amount of separation of the glass-side decorative portion 21 a are also corresponding to the maximum step formed. It has been maximized. The maximum separated state of the glass-side decorative portion 21a is kept constant toward the lower side region of the side portion. A rainwater receiving groove 28 is defined so as to open to the inner peripheral side in the space where the glass-side decorative portion 21a in the side portion is separated from the glass surface.

If the glass-side decorative portion 21a is separated from the surface of the window glass 1, the posture of the molding may become unstable and may be deformed. However, as described above, the side molding 2C is relatively hard. Since it is made of the material P1, the posture and shape of the main body molding 2 are well maintained.

On the other hand, at this time, since the exterior surface portion of the decorative portion 21 that constitutes the appearance of the molding is formed of the same resin material P3 over the entire length, the appearance design of the molding is a series of seamless design states. It is supposed to be maintained.

In such a vehicle body side mounting structure of the windshield 1, the rainwater dripping on the windshield 1 is guided to the inner peripheral wall surface of the glass side decorative portion 21a, and the rainwater collected in the side portion is The water is guided to the inside of the rainwater receiving groove 28 and discharged to a predetermined portion.

The wind molding is performed by inserting the window glass 1 into the window frame side in advance as in the present embodiment, and then in the gap between the peripheral edge of the window glass 1 and the vehicle body panels 3, 4. The window glass 1 may be attached to the window glass 1 or the window glass 1 may be attached with the window molding attached. Also, if the corner portion of the sub molding 3 is not fixed to the main molding side, the corner portion of the sub molding 3 can be formed of a hard material.

Next, the main molding 32 of the wind molding according to the second embodiment shown in FIGS. 7 and 8 is also mounted in the gap between the upper edge of the windshield and the roof panel 32A. And a side molding 32C mounted in a gap between both side edges of the windshield and the pillar panel, and a corner molding 32B connecting the upper molding 32A and the side molding 32C in a curved shape. The moldings 32A, 32B, 32C are integrally and continuously extruded.

The main body molding 32 is formed by integrally extruding an elastic material such as rubber or synthetic resin into a long strip shape by a predetermined extrusion molding device. In addition to having leg portions 322 inserted in the gap, a decorative portion 321 that covers the space between the window glass and the vehicle body panel from the vehicle exterior side is provided. The decorative portion 321 and the leg portion 322 form a substantially T-shaped cross section orthogonal to the longitudinal direction.

The leg portion 322 is made of a hard material P1 in the side molding 32C and the upper molding 32A, and is made of a flexible material P2 in the corner molding 32B. A metal wire 323 as a core material is embedded in a connecting portion between the leg portion 322 and the decorative portion 321. Further, a support piece 324 for supporting the lower part of the windshield is provided over the entire length at the vehicle inner edge of the leg portion 322. A glass fitting support groove for receiving the window glass is defined between the support piece 324 and the decorative portion 321 with a uniform cross-sectional shape over the entire length. Further, an elastic lip piece 325 that projects toward the wall surface of the vehicle body panel and is pressed against the wall surface of the vehicle body panel is provided in the middle portion of the leg portion 322 toward the outside of the vehicle. This elastic lip piece 325 is made of a flexible material P3 over its entire length.

The decorative portion 321 has a glass side decorative portion 321a and a panel side decorative portion 321b extending from the vehicle outer side end of the leg portion 322 to the wind glass side and the vehicle body panel side, respectively, and the entire length of the molding. It has a uniform wall thickness and shape. The vehicle exterior surface portion of the decorative portion 321 is made of the same resin material over its entire length and is made of the same flexible material P3 as the elastic lip 325 described above. The inner portion of the decorative portion 321 is made of the same hard material P1 (side portion and upper portion) and the soft material P2 (corner portion) as the leg portion 322.

As in the first embodiment, the height of the leg portion 322 in the vehicle-outside direction is set short in the upper mold 32A and set slightly long in the side molding 32C. In the side molding 32C in which the height of the leg portion 322 is enlarged, a thick portion formed by bulging the leg portion 322 toward the inner peripheral side is provided. The inner periphery of the bulged thick portion A rainwater receiving groove is defined by the side wall surface and the glass surface of the decorative portion 321. The size of the rainwater receiving groove is changed in proportion to the rising height of the thickened portion of the leg portion 322. It is possible to provide such a thickened portion on the leg portion 322 by, for example, Japanese Patent Laid-Open No. 3-128721.

Also by the molding according to the second embodiment as described above, the rigidity of the rainwater receiving groove forming portion (side portion) is increased, the bendability of the corner molding 32B is ensured favorably, and the difference in bending circumferential length is increased. There is no problem such as wrinkles. Further, since the decorative portion 321 that constitutes the exterior of the molding is formed of the same resin material P3 over the entire length, the appearance design of the molding is maintained in a seamless and good state.
